Comb and method of making



Sept. 25, 1956 D. P. IESERSEK COME AND METHOD OF MAKING Filed July 5, 1951 DiI/QHfOT? Danie Pensions Laser-567i by 7155 fliforrz GAL /0Q United States This invention relates to improvements in hair combs, as Well as in methods of mass producing them.

One object of this invention is to provide a novel and improved comb structure having a tooth formation which has better untangling apparatus than combs with teeth of the usual construction.

Another object of this invention is to provide a novel comb in which the teeth have smooth rounded ends, and which at the same time have desirable flexibility.

An object of this invention is to provide novel methods of manufacturing combs of the above characteristics by mass production methods, economically.

A more specific object of the invention is the provision of a novel method of making combs of two parts, of which one part is a unitary tooth structure having teeth with double legs united at one end to the handle and at th other to each other.

A more specific object of the invention is to provide a novel molding method by which some combs may be made either of two pieces or of one piece.

Other and more detailed objects of the invention will be apparent from the following description thereof in connection with the attached drawings.

In the accompanying drawings,

Figure 1 is a front elvational view of a comb in accordance with this invention;

Figure 2 is an end elevational view of the tooth portion of the comb with the handle removed;

Figure 3 is a cross-sectional view taken on the line 33 of Figure 1;

Figure 4 is a front elevational view of a portion of a modified comb structure in accordance with this invention; and

Figure 5 is an end elevational view thereof.

A characteristic of the structures of the combs herein illustrated is in the presence of generally U-shaped teeth with rounded ends, which type of structure does not irritate the scalp of the user and is unusually eifective in combing out the hair and untangling it. A serious problem of economical manufacture by mass production methods is presented when attempting to manufacture combs having teeth of this form. The basic object of this invention is to provide novel methods of producing such combs. In developing these methods novel comb structures resulted.

The comb of Figures 1 to 3 inclusive consists of two parts, a toothed member and a handle. The teeth T consist of a pair of substantially straight legs united at one end by a smoothly curved connecting piece 11. The opposite terminal ends of the legs 10 are united respectively by means of integral bars 12 and 13. A handle 14 of suitable utilitarian and decorative characteristics is provided. The handle is united to the bar portions 12 and 13 of the toothed assembly along the edge thereof, in any suitable manner, as by means of an adhesive the nature of which will depend upon the material used in forming the toother assembly and the handle.

In accordance with this invention it is proposed to mold these two major parts from hard rubber and synthetic and natural moldable plastic materials of which many are known in the molding arts. The novelty of atent this structure resides in the conception of structural elements which are capable of being molded and united to form a complete comb. Combs having teeth individually forming substantially U-shaped members are not readily moldable because of the difiiculty of providing a mold of suitable configuration and easily separable to permit removal of the finished product. By the method herein disclosed it is easy to mold the tooth structure in a single piece, comprising a plurality of teeth T, formed integral with the connecting ribs 12 and 13. Thus the ribs provide serial connection of the teeth. The handle 14 may likewise be readily molded as a continuous piece and the two structures can then be united as suggested above by an adhesive, or in the case of some of the thermo-setting plastic materials, by heat and pressure. It will be understood by those skilled in the art that either by adhesion or thermo-setting, the handle and teeth are united in effect to provide an integral, one-piece comb.

In Figures 4 and 5 is illustrated a single piece comb which may likewise be readily molded from any of the available molding materials. This comb is shown gen-- erally at 2p and as molded consists of a slide bar 22 of fiat, generally elliptical form in cross-section. The bar or body member 22 is molded with a longitudinal passage 21 extending therethrough, likewise of generally flat elliptical form in cross-section. The teeth TT are formed by means of a gang saw S, consisting of a plurality of rotatable concentric circular saws so spaced and of such thickness as to form teeth of proper proportions. The molded bar 22 is fit into these saws to a point coincident with a plane tangent to the inner end of the passage 21, thereby forming a plurality of hollow, generally U-shaped teeth TT integral with the remaining upper portion of the bar, to provide a handle.

It will be noted that by each of these methods, hollow, rounded end teeth are provided, which as stated above, provides a tooth formation which is effective for combing the hair without scalp irritation and with little interference of tangled and knotted hair.

From the above description it will be apparent that the novel methods and modifications herein disclosed are capable of some variation without departure from the invention herein disclosed. I do not, therefore, desire to be limited to the illustrative embodiments in the attached drawings, but only as required by the appended claims.

What is claimed is:

1. A method of making a comb which consists in molding a unitary elongated body of generally elliptical crosssectional shape with a longitudinal passage therethrough and cutting slots in said body laterally thereof into said elongated body and said longitudinal passage to form a plurality of teeth.

2. in the method of claim 1, said cuts being made inwardly from one edge of said body to a plane substantially tangent to a longitudinal edge of said passage.

3. In the method of claim 1, said passage being of elliptical cross-sectional form and said cuts intersecting said body from one side edge to a point substantially coincident with the far end of said passage.
